An expulsion of trapped air from the vagina after an act of sexual intercourse or, less commonly, vigorous cunnilingus, accompanied by a loud report resembliong the expulsion of methane gas from the anus. In women with extremely prominent labia and tight vaginas, a "pussy fart" may resemble a growling noise not unlike that of a feline, which may have given rise to the term "pussy" for the female genitalia.

I was enjoyng a cigarette after banging Roz and dang! Her pussy farted loud as a howitzer and nearly blew out my smoke!

1) An unwanted or embarassing noise during an otherwise thoroughly enjoyable activity.
2) An annoying braggart, an unmitigated idiot.
3) The sound of air escaping the vagina while being pistoned by a rock hard penis.

That pussyfart Del needs to get a life.
I do hope that was a pussyfart and not something else.
